See also Fig. 1 to Fig. 6, the utility model battery welding clamp is installed on the workbench 9, comprise battery connecting gear 1, battery jacking mechanism 2, battery hold-down mechanism 4, battery switching mechanism 3 and top mechanism 5, this battery jacking mechanism 2, battery hold-down mechanism 4 and top mechanism 5 constitute the battery clamp system.

This battery connecting gear 1 comprises transmission power cylinder 11 and the slide unit 12 that but level moves forward and backward by its piston rod driving, and this transmission power cylinder 11 is fixedly mounted on the workbench 9, and slide unit 12 is mounted in the top of transmitting power cylinder 11.The rear end of slide unit 12 is installed with propulsion power cylinder 13, be connected with battery push pedal 14 on the piston rod 131 of this propulsion power cylinder 13, and be arranged with elastic component (as spring) on the piston rod 131, these elastic component two ends are connected to respectively on propulsion power cylinder 13 and battery push pedal 14 sides, thereby by the effect of propulsion power cylinder 13 battery push pedal 14 are moved forward and backward in the horizontal direction.In addition, front end at this slide unit 12 is installed with in order to place the material box 15 of battery, the bottom of this material box 15 is provided with discharging opening 151, the shape of this discharging opening 151 is consistent with battery 8 with size, and this discharging opening 151 is aligned with the position of battery push pedal 14 and is positioned on the movement locus of this battery push pedal 14.

Battery jacking mechanism 2 is fixedly mounted on the workbench 9, comprises holding out against power cylinder 20, and in the present embodiment, this holds out against power cylinder 20 is two bar cylinders of CXSM10-25 for model.Battery switching mechanism 3 comprises upset power cylinder 30 and battery loading plate 31, this upset power cylinder 30 is fixedlyed connected with the piston rod 201 that holds out against power cylinder 20, it drives rotating part 301 rotations, these rotating part 301 1 ends are fixedlyed connected with the side of battery loading plate 31, thereby this battery loading plate 31 can overturn under the driving of upset power cylinder 30.In the present embodiment, this upset power cylinder 30 is the rotary cylinder of CQR2BS10-180 for model, when these upset power cylinder 30 starts, this battery loading plate 31 can be realized the upset of 180 degree.In order to guarantee that battery 8 is positioned at same position when welding before and after upset, the rotating part 301 of upset power cylinder 30 is the centers that are positioned at battery loading plate 31 sides with the junction of battery loading plate 31.The position of corresponding discharging opening 151 is provided with accepting groove 311 on this battery loading plate 31, this accepting groove 311 in order to location battery 8 in wherein.

Battery hold-down mechanism 4 is installed on the battery loading plate 31, comprise that one compresses the compact heap 43 that power cylinder 40 reaches by its driving, this compresses power cylinder 40 is a cylinder, and its piston rod 401 is hinged by an articulated joint 41 and a fixed head 42, and this fixed head 42 is the upper ends that are fixedly mounted on compact heap 43.This compact heap 43 roughly is " L " type, comprises a forced section 430 and the force section 431 that is connected with its one, is 90 degree angles between forced section 430 and the force section 431.This forced section 430 is connected with fixed head 42, and this force section 431 can press on the surface of battery case.And the intersection of force section 431 and forced section 430 is to be hinged on the battery loading plate 31 by a hinged support, thereby this compact heap 43 can be overturn in the certain angle scope by this hinged support.When the piston rod 401 that compresses power cylinder 40 stretched out, then forced section 430 flipped an angle forward, and makes force section 431 compress battery 8 shells; When the piston rod 401 that compresses power cylinder 40 is return, then pull back forced section 430, thereby battery 8 shells are unclamped in force section 431.

Top mechanism 5 comprises the top pedestal 53 that is fixed on the workbench 9, these top pedestal 53 1 sides are equipped with top slide block 52, these top slide block 52 tops are equipped with copper top 51, by the position of up-down adjustment top slide block 52, thereby make the position of copper top 51 meet the height that battery welds.

In addition, this battery welding clamp also comprises inductor 6, and this inductor 6 is mounted in the bottom surface of battery loading plate 31, and this inductor 6 promptly starts the program that entire cell is welded after sensing battery 8.Under battery loading plate 31, also be provided with slide plate 7.

The operating process of this battery welding clamp is as follows: weld jig starts back (must be provided with to give weld jig to begin the order of action) in program, at first the transmission power cylinder 11 driving slide units 12 by battery connecting gear 1 move to battery loading plate 31 positions, this moment, discharging opening 151 was aligned with the accepting groove 311 of battery loading plate 31, and propulsion power cylinder 13 drives battery push pedal 14 battery in the material box 15 8 is delivered in this accepting groove 311; After inductor 6 is sensed battery 8, then make battery jacking mechanism 2 and the action of battery compacting machine 4 structures, battery connecting gear 1 resets, 2 actions of battery jacking mechanism, entire cell switching mechanism 3 is sent forward, and simultaneously battery hold-down mechanism 4 compresses battery 8, and battery 8 held out against copper in top mechanism 5 and came directly towards 51 positions with to battery in place this moment, battery hold-down mechanism 4 drove compact heaps 43 upsets and made force section 431 compress the peristome of battery 8 this moment, so that battery container is fitted tight with cover plate; When having welded a rear flank, battery jacking mechanism 2 unclamps, rotating part 301 rotations of battery switching mechanism 3, drive

entire cell

8 and 4 upsets of entire cell hold-down mechanism by battery loading plate 31, what make that battery 8 do not weld one faces up, can not drop out so battery 8 compacted piece 43 be pressed in battery loading plate 31 on because battery hold-down mechanism 4 does not unclamp this moment; After battery 8 was translated into another side, battery jacking mechanism 2 moved once more, as last time, battery 8 was held out against on the copper top 51 of top mechanism 5 with location once more, and workbench is walked for 9 times, can realize the welding of battery 8 corresponding side surface.

After welding was finished, workbench 9 resetted, and battery jacking mechanism 2 is return once more, and in this process, battery switching mechanism 3 resets, and battery hold-down mechanism 4 unclamps.When battery switching mechanism 3 resetted upset, battery 8 just can skid off from battery loading plate 31, and the slide plate 7 under dropping on, by this slide plate 7, battery 8 can slide to desired position.

After battery 8 skidded off, each mechanism all was returned to initial condition, prepared the circulation of next time.At this moment, if there is not battery 8 in the material box 15, then inductor 6 inductions are less than the existence of battery 8, and then weld jig can be parked in this initial condition and no longer action, puts into battery up to the operator in material box, and starts once more.

In the utility model, the adjustable height of battery connecting gear 1 can accurately be pushed into from material box 15 in the battery loading plate 31 thereby be convenient to battery; The fixed-site of battery jacking mechanism 2 and top mechanism 5, thus be convenient to the assembling of whole weld jig; Battery jacking mechanism 2 and battery switching mechanism 3 can be realized holding out against and overturning battery with an existing pendulum cylinder of stretching; Be provided with elastic component between battery push pedal 14 and the propulsion power cylinder 13, can reduce the pressure of 13 pairs of battery switching mechanisms 3 of propulsion power cylinder.

In the utility model, because adopt the battery switching mechanism, so the automatic turn-over can realize the battery welding time; By the setting of battery connecting gear, can be with the battery automatic transport to the welding position; Setting by battery clamping and hold-down mechanism can realize the automatic clamping of battery.By the setting of this battery welding clamp, can enhance productivity, alleviate operative employee's labour intensity, and can guarantee the quality of welding.
